How to Grow Microgreens on Your Windowsill in 10 Days

Microgreens are young edible seedlings harvested just after their first leaves appear—packed with flavour and nutrients, and perfect for small Indian homes where a sunny windowsill is all the garden you have. They need no fertiliser, no big pots and very little space, making them ideal for apartments, balconies and terraces. In roughly 10 days you can go from dry seed to a fresh, snippable harvest for salads, dals, sandwiches and garnishes.

What You Need to Get Started

• A shallow tray or reused container, 3–5 cm deep, with drainage holes
• A thin layer of light seed-starting mix, cocopeat, or a damp paper pad
• Fast-growing seeds like moong, methi, mustard, radish, sunflower or peas
• A spray bottle for misting and a bright windowsill with indirect light

Step 1: Sow Densely and Cover

Fill your tray with about 2–3 cm of moist growing medium and press it flat. Scatter seeds thickly and evenly across the surface so they almost touch, then press gently—do not bury them deep. Larger seeds like peas, sunflower and moong benefit from soaking in water for 6–8 hours first. Cover the tray with another tray, a plate or a sheet of paper to keep it dark and humid for the first 2–3 days while the seeds germinate.

Step 2: Give Light Once They Sprout

When you see tiny green shoots, uncover the tray and move it to a bright windowsill. In India's strong climate, indirect or gently filtered light works best—harsh midday sun through glass can cook delicate seedlings and dry the tray out fast. A north- or east-facing window is ideal. If your only spot is very hot, shift the tray back a foot from the glass or use a light curtain to soften the rays.

Step 3: Water Gently and Watch for Mould

Keep the medium consistently damp but never waterlogged. Mist the surface once or twice a day, and where possible water from the base by pouring a little into the tray beneath—this keeps leaves dry and discourages fungus. Good airflow matters, especially during the humid monsoon, so avoid crowding trays against a wall and run a fan nearby if the air feels still and heavy.

Fuzzy white growth that vanishes when misted is usually harmless root hair. A slimy, cobweb-like grey patch is mould—thin your seeding next time and improve airflow.

Step 4: Harvest at 8–12 Days

Your microgreens are ready when the first pair of true leaves appears, usually on days 8 to 12 depending on the crop and the warmth. Using clean scissors, snip the stems just above the soil line in the morning when they are crisp. Most microgreens do not regrow after cutting, so simply compost the spent roots and resow the tray for a continuous supply. Rinse lightly and eat fresh, or store in the fridge for a few days.
